1N5336A/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5336A/TR8 is a silicon unidirectional Zener diode with a nominal voltage of 4.3V and a tolerance of ±10%. It operates in the T-18 axial leaded package, dissipating up to 5.0 watts at 25°C. The device withstands operating temperatures from -65°C to +150°C and features a maximum dynamic impedance of 2.0 ohms at a test current of 290 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad range of operating currents and temperatures
• Withstands high surge stresses without failure
• Exhibits minimal changes in voltage relative to current variations
• Remains nonsensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against transient overvoltages
• Reference voltage generation for analog signal processing

Single Zener Diodes Procurement Notes

Verify that the part number suffix matches the required tolerance and packaging specifications. Confirm RoHS compliance status by checking for the e3 suffix if lead-free components are mandated. Ensure the TR designation aligns with tape and reel handling requirements for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when a 4.3V reference with ±10% tolerance is required. Consider the 5-watt power dissipation capability and low thermal resistance design for applications demanding high DC currents. Verify adequate heat sinking or FR4 PCB copper pad dimensions to maintain safe junction temperatures during operation.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5333 through 1N5388B series of 5.0 watt Zener diodes. The series offers a wide selection of voltages ranging from 3.3 to 200 volts. Different tolerance levels are identified by specific suffix letters on the part number, allowing for precise configuration based on circuit requirements.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. Military equivalent screening levels can be obtained by adding MQ, MX, or MV prefixes respectively to the base part numbers.
